Abstract
The utility model relates to a pre-filling and sealing syringe assembly, in particular to a luer lock adapter snap ring for a pre-filling and sealing glass syringe, which comprises a cylindrical snap ring main body part, wherein the outer wall of the snap ring main body part is uniformly provided with a plurality of axial convex edges, and the inner wall of the snap ring main body part is provided with a spiral groove; the bottom of snap ring main part is equipped with the snap ring extension, be provided with the bead extension on the outer wall of snap ring extension. The utility model discloses an extension design makes luer lock head snap ring wrap up the all parts of the conical head on glass needle tubing top completely, has both solved the conical head and has cracked easily in production and use, broken problem, can realize again that luer lock adapter snap ring and glass needle tubing shoulder pass through UV and glue solidification technology and form a whole to solved the easy not hard up problem of traditional product snap ring, thoroughly solved because of the not hard up weeping that causes of luer lock head snap ring, gas leakage and lead to the product to produce mycotic problem.
Description
Technical Field
The utility model relates to a embedment syringe subassembly in advance, specifically speaking relates to a luer lock adapter snap ring for embedment glass syringe in advance.
Background
The luer lock adapter clamping ring is mainly used for pre-filling and sealing a glass syringe and mainly used for pushing and pressing a glass needle tube conical head to fasten a luer lock head, so that the problem of needle tube sealing is solved. The conventional luer lock adapter snap ring product suffers from the following problems: 1. the length is too short, and a part with bare leakage is arranged between the conical head of the glass needle tube and the clamping ring after the clamping ring is pushed and pressed, so that the conical head of the glass needle tube is easy to break and break in production and use; 2. only push and press on glass syringe conical head, rotate easily and lead to the tapered end to become flexible, cause the syringe to seal the effect and destroy, form weeping, gas leakage scheduling problem.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's defect, a luer lock adapter snap ring for embedment glass syringe in advance to solve above-mentioned technical problem.
In order to achieve the above object, the utility model adopts the following technical scheme:
a luer lock adapter snap ring for a pre-filled glass syringe comprises a cylindrical snap ring main body part, wherein a plurality of axial convex edges are uniformly arranged on the outer wall of the snap ring main body part, and a spiral groove for assembling a luer lock head is formed in the inner wall of the snap ring main body part; the method is characterized in that: the bottom of snap ring main part is equipped with the snap ring extension, be provided with the bead extension on the outer wall of snap ring extension.
Furthermore, the clamp ring extension part and the clamp ring main body part are of an integrated structure formed in one step by a mould, a flat cylindrical counter bore and a truncated cone-shaped counter bore are arranged in the clamp ring extension part, the counter bore is located above the counter bore, and a jack for inserting a conical head at the top end of the glass needle tube is arranged above the counter bore.
Furthermore, the surface between the top end and the bottom end of each rib extension body is an inclined surface.
Has the advantages that: compared with the prior art, the utility model discloses an extend the extension design, make luer lock head snap ring wrap up the all parts of the conical head on glass needle tubing top completely, both solved the conical head and split easily in production and use, broken problem, can realize again that luer lock adapter snap ring and glass needle tubing shoulder pass through UV and glue ultraviolet irradiation solidification technology and form a whole, in order to solve the easy not hard up problem of traditional product snap ring, thoroughly solve never because of the not hard up weeping that causes of luer lock head snap ring, leak gas and lead to the product to produce mycotic problem.

Detailed Description
The invention is further described with reference to the following figures and specific embodiments.
Example (b):
referring to fig. 1 and 2, the luer lock adapter snap ring for a pre-filled glass syringe according to the present embodiment includes a cylindrical snap ring main body portion 1, a plurality of axial protruding ridges 11 are uniformly arranged on an outer wall of the snap ring main body portion 1, and a spiral groove 12 for assembling a luer lock head 3 is arranged on an inner wall of the snap ring main body portion 1, as shown in fig. 3 and 4. The bottom end of the snap ring main body part 1 is provided with a snap ring extension part 2 (the part below the dotted line in fig. 1 and fig. 3), the outer wall of the snap ring extension part 2 is provided with a convex edge extension body, and the surface between the top end and the bottom end of each convex edge extension body is an inclined surface. The clamp ring extension part 2 and the clamp ring main body part 1 are of an integrated structure formed by a die in one step, a flat cylindrical counter bore 21 and a circular truncated cone-shaped counter bore 22 are arranged in the clamp ring extension part, the counter bore 21 is located above the counter bore 22, and a jack 13 for inserting a conical head at the top end of the glass needle tube 4 is arranged above the counter bore 21.
During the assembly, 4 top conical heads of glass needle tubing insert the jack 13 in the luer lock adapter snap ring, because the utility model discloses luer lock adapter snap ring is through extending the extension design for luer lock head snap ring has wrapped up the all parts of the conical head on glass needle tubing top completely, has both solved the conical head and has split easily in production and use, broken problem, can realize again that the snap ring extension 2 of luer lock adapter snap ring lower part and the shoulder of glass needle tubing 4 pass through UV and glue through ultraviolet irradiation solidification technology and form a whole, thereby solved the easy not hard up problem of traditional product snap ring, thoroughly solved because of the not hard up weeping that causes of luer lock head snap ring, gas leakage and lead to the product to produce mycotic problem.
The foregoing shows and describes the basic principles, features and technical features of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and the scope of the invention is to be protected. The scope of the invention is defined by the claims and their equivalents.
